Move -help and -version to the front of the man page options.

Move -help and -version to the front of the man page options.
The man pages had -verbose and -help listed at the end of the synopsis.
This put them after mandatory arguments in some cases, e.g. post(8).
Put then at the front, swapping the order so -help is first, as novices
will want to know -help exists early on, and others can simply skip over
them rather than encounter them at the end when they're trying to track
the combinations of what they've read so far.
